The NSTA’s interactive Decommissioning Benchmarking Report, published annually, uses thorough data analysis to provide insights into industry’s performance in post-CoP running costs, well P&A, removals, project management and onshore disposal.
Sharing this information can help operators identify opportunities to continuously improve their decommissioning project planning and execution, and cost-efficiency.
The benchmarks were developed with input from industry and include the cost and duration of well P&A, which can be split and viewed by mechanical status and region.They are derived from data gathered via the annual UKCS Stewardship Survey, in alignment with the OEUK Decommissioning Work Breakdown Structures.
The 2025 Report sees a significant increase in the quality and quantity of ‘actual’ i.e. executed well decommissioning data points as well as augmented report functionality and interactivity available to the reader.
This includes the launch of an interactive tool containing more than 1,100 validated UKCS well decommissioning data points, cross-correlated for the first time with barrier data contained within the NSTA’s Well Operations Notification System (WONS), as well as a range of dynamic filter options.

The NSTA has also recorded a short video to help people make best use of the report.
